3.11 JTAG Flash Programming

The DLPC900 JTAG Programmer Tool is included in the DLPC900REF-SW bundle allowing a user to program the bootloader image into the flash using the JTAG boundary scan connector if, for example, the bootloader becomes corrupted and the board is rendered inoperable. The tool can also be used for updating the entire firmware image. Programming the entire firmware image using this method may take a long time. It is suggested to program only the bootloader using this method, and then use the DLPC900 LightCrafter GUI with a USB connection to upload the entire firmware image. The following steps are for programming only the bootloader image.

Important: Before using JTAG to reload the bootloader, first install the BOOTHold jumper (J12) and turn the system on. The system shows connected, but does not recognize the attached DMD. Manually select the radio button that matches your DMD and go to the firmware tab and select the FW image and reprogram. Then power down, remove the BOOTHold jumper and restart the system. Reprogramming in this manner often recovers a system without requiring reloading the bootloader through JTAG.

The DLPC900 JTAG Programmer Tool requires the UM232H module with modifications, which is manufactured by Future Technology Devices International Ltd (FTDI Chip), . The UM232H module can be purchased from Digi-key with the following part number: 768-1103-ND. The driver can be downloaded from the FTDI website (www.ftdichip.com). Select the VCP CDM WHQL Certified driver for Windows.

Make the following modifications to the UM232H and use Figure 4-24 and Figure 4-25 as a guide.

Connection Details

  1. BUS power configuration
    • Short PIN #2 and PIN #3 of J1 (SYS PWR)
    • Short PIN #2 and PIN #3 of J2 (I/O PWR)
  2. J2-6 → GND (PWR)
  3. J2-7 → TCK (OUTPUT)
  4. J2-8 → TDO1 (OUTPUT)
  5. J2-9 → TDI (INPUT)
  6. J2-10 → TMS1 (OUTPUT)
  7. J2-11 → TRSTZ (OUTPUT)

Choose the driver found in the CDM WHQL Certified zip folder and allow driver installation to complete. Install a jumper at J10/J12 for the DLP LightCrafter Dual DLPC900 EVM. Populate R118 with a 0 ohm resistor and depopulate R117 near the center of the main board. Connect the JTAG signals at J11 on the DLP LightCrafter Dual DLPC900 EVM to the UM232H module as shown in Figure 4-25. Finally, connect the UM232H to the PC with USB cable.

Note:

The JTAG programmer has its own copy of the FlashDeviceParameters.txt file which is located in the DLPC900REF-SW-x.x.x\\DLPC900REF-JTAG directory of the DLPC900REF-SW bundle. Please see Section 4.10 for instructions on how to edit this file to match your flash. If you have already made changes to the FlashDeviceParameters.txt file in the DLPC900REF-SW-x.x.x\DLPC900REF-GUI\Flash directory that work with the GUI, you may copy that file to the DLPC900REF-SW-x.x.x\\DLPC900REF-JTAG directory

Start the DLPC900 Flash Programmer program and select the BoardFile.brd and the bootloader.bin included the install folder. Select USB as communication method from the Settings menu.

Power-up the EVM board and click the Detect Chain tool button. The tool detects the DLPC900 in JTAG chain and shows two DLPC900s. Now click on one of the DLPC900 to select it. On the EVM notice the Red/Green LEDs light up (D6/D7 or D8/D9) to confirm which DLPC900 is currently selected.

Click the Flash Info button and confirm the correct flash part is detected by the tool. Using the Flash Erase button select the first sector(s) (to cover first 128 kilobytes) and erase these sector(s).

Once sector erase is complete, set the Start Address (HEX) to 0x00000000 and set the Size (HEX) to 0x20000. Then click the Program Flash button, and then wait until write is complete.

Note: Make sure that verify is 100% complete!
Do the same Erase and Flash for the second DLPC900. Finally remove the UM232H JTAG and remove jumper at J10 and J12, and then cycle the board power to the EVM. Plug in a USB cable between the EVM and the PC and allow the PC to detect the EVM USB connection.

Once the EVM is detected, go to the firmware page and select the primary and secondary image files for your attached DMD EVM and program them.
